Re: Micropython as debug shell for ESP32 (and its OLED)
6 weeks ago I did kill my 2nd ESP32+OLED module due to bad soldering. I ordered two new modules that day, and they arrived today: https://stamm-wilbrandt.de/en/forum/IMG_20180302_183657.jpg I looked into this thread and the steps needed to get my "debug MicroPython" flashed seem not to be completely...

Re: Micropython as debug shell for ESP32 (and its OLED)
I went a step further after I exchanged the two unidirectional MOSFETs with a TB6612FNG motor driver, see bottom photo. Just saw that these modules cost <1$ with free shipping today. http://stamm-wilbrandt.de/en/forum/TB6612FNG.png So this is kind of another level of debugging, not single pins anym...

Re: Micropython as debug shell for ESP32 (and its OLED)
https://cdn.instructables.com/FAK/RKQ0/J3YPR3IJ/FAKRKQ0J3YPR3IJ.MEDIUM.jpg Thank you so much! The "Flash ..." GPIO labelling for 6-8 and 11 might be an explanation on ESP32 hang when I set any of those to OUTPUT as in previous posting. "SND" being "GND" is funny, and yes, I measure 0V on that pin. ...

Re: Micropython as debug shell for ESP32 (and its OLED)
Update on pin verification, see pin naming for my ESP32 module in photo detail below. Via google search I did find out that RX is 3 and TX is 1, which I verified as above, Then I investigated all GPIO numbers N in 0-31 [by executing "pin = machine.Pin(N, machine.Pin.OUT)" ]: 20,24,28-31 invalid 9,10...

Re: VGA output: Can SPI make and send infinite circular buffer?
Nice project. I did a lot of experiments with DueVGA: https://github.com/stimmer/DueVGA A much less capable microcontroller (84MHz Arduino Due) with much less memory (96KB ram). You may want to lookup stimmer's DueVGA code on Github for how he did. Allows for 1024x675 monochrome and 320x240 color, o...

Re: Micropython as debug shell for ESP32 (and its OLED)
I did solder headers to one of my ESP32 modules and used the still flashed Micropython to verify the pins: http://forum.arduino.cc/index.php?topic=495555.msg3553490#msg3553490 Only pins left where I need to find out how to test are the non-numbered pins SVP, S1, CM, S0, CL, SND, SVN, RX, TX, all oth...

Re: Micropython as debug shell for ESP32 (and its OLED)
I wanted to get a wireless ESP32 debug solution and tried Telnet servers in MicroPython for that. Unfortunately there is an issue with "dupterm()" not being implemented in ESP32 MicroPython, see this thread: https://forum.micropython.org/viewtopic.php?f=18&t=3997 In this thread user loboris pointed ...
